When windows are used together with the RUI,
a new kind of window manager results.
For example, while waiting in lounge or other waiting area,
a user might define walls around the lounge as various windows.
In this way screen real-estate is essentially infinite.
Although not all screens are visible at any one time, portions
of them
become visible through the WearComp glasses, when they are looked at.
Others in the lounge need not be able to see them, unless they
are wearing similar glasses and the user has also permitted them
access to these windows (as when two users are planning upon
the same calendar space).

There are no specific boundaries in this form of window manager.
For example, if the user runs out of space in the lounge, he or she
can walk out into the hall and create more windows on the walls of
the hallway leading into the lounge. It is also easier to remember
where all the windows are when they are associated with the real world.
Part of this ease of memory comes from having to walk around the space,
or at least turn one's head around in the space.

This window manager, called RWM, also provides means of making the
back of the head ``transparent'', in a sense, so that one can see
windows in the front as rightside-up and windows behind as
upside-down. This scheme simply obeys the laws of projective geometry.
Rearview windows may be turned on and off, since they are distracting
for concentration, but they are useful for quick navigation around
a room.
